摘要
The vulnerability analysis is an estimation of the degree of loss or damage that would result from the occurrence of a natural phenomenon of given severity. Here, we can estimate the area of land vulnerable to loss, the number of displaced resident population considered at risk and the cost of protective engineering structures vulnerable to wide range of risk for any coastal extreme events. The present study therefore is an endeavour to develop a probability of coastal vulnerability (p) and their intimate coastal vulnerability score (CVS) for the coastal blocks of maritime Balasore block in Odisha considering the change of four resources (land, water, house/shelter and transport) during pre and post status of coastal extreme events like cyclone, flood, storm surges, beach erosion, wave action and salinity problem, which are frequent in nature at the low lying coastal stretch. In this study it emphasises on five groups that are likely to have least protection against hazard. Nature and composition of such highly vulnerable groups may vary from place to place and situation to situation. Zones of vulnerability to coastal natural hazards of different magnitude are identified and shown on C.D block map with Gram Panchayat level. However, principle of binomial test (as applied in sign test) can be use for determining the probability with respect to each of the selected variables using the mean effects of those said coastal extreme events data base. After getting the vulnerability of probability, it has been multiplying with the respective population data to calculate the CVS of a particular coastal Gram Panchayat (considered spatial scale to study). This is the first such study that has been undertaken for a part of the Balasore coast. The map prepared for the Balasore coastal district under this study can be used by the state and district administration involved in the disaster lessening and executive plan.
